On the world of Terra Set, where the night is twice as long as the day and the moon more powerful than the sun, live the Star Mages. Essential to supporting the crops that feed the masses, they are protected men, revered, yet still mistrusted.

An ancient myth tells of a female mage born at the Silver Minute. She holds a magic that, shared with a mate, will be unequaled. Riena is that mage.

A ruthless king will stop at nothing to force Riena to take his son as mate. Her life and freedom depend on one challenge--hide as a man.
